Chapter 8 - Tunable White

Note: This feature is only available on Response SN3s with Firmware 184 or above ( as well as Response Radios with firmware version 2.0 or higher). It is also worth mentioning that the current release and capability of control for this feature via app will first be introduced in the new Response App as part of this release, and followed by an update (patch release) in the original Response IR App. Stay tuned for the patch release notes.

The new Organic Response 2021.1 release now has support for Tunable White feature. This feature is automatically made available with the released firmware (v184 or higher) for luminaires that have variable color temperatures (commonly known as Device Type 8, or “DT8”) drivers. Such devices/drivers can now be controlled using an Organic Response Response SN3 even in combination with existing DT6 drivers.

DT8 drivers are single address multipath channels recently introduced for Tunable White applications. These drivers use one address to achieve tunable white, or variable colour temperature, applications. DALI Type 8, also known as DALI 209, is a DALI compatible device (Device Type 8). Such devices allow a user to change light colour or colour temperature as well as its intensity.

DALI Type 8 uses a single DALI short address to control 2 or more outputs on a special DALI Type 8 driver or ballast, thereby reducing the number of both DALI short addresses and DALI drivers needed to provide this colour changing capability. Saving on both cost and complexity. Combined this means that our simple and cost-efficient plug-and-play solution is ready to support a whole new generation of luminaires.
